WELT-GUIDE FOR SEWING WATER-TIGHT INSEAMS.

Specification of Letters Patent.

Patented Feb. 13, 1912.

Be it known that we, J AMEs E. MOP ER- soN and EDWARD E.- ORR, citizens of the United States, residing, respectively, at Canton and Weymouth, in thecounty of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Welt-Guides for Sewing Water Tight Inseams; and we do he'rebyfdeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same. 1

The present invention relatesto a wok guide attachment for sewing machines adapted to unite the weltto the upper and insole. 3

In the construction of the usual Goodyear welt shoe, the finished side of the welt-is presented to the lasted insole and upper and sewn thereto by a line of stitching running .along the inner edge of the welt (or upper edge of the welt, if the position of the welt as it is sewn to the inverted shoe is considered). The outer or lower edge of the welt is then beaten flat and sewn to the edge of the out-sole. This leaves a crease between the welt and the upper through which the water may ooze into the .shoe. In making the WaterprooPshoe herein described, the welt is sewn to fill in and effectively close this crease against the access of water, making a watertight inseam. To make this watertight inseam the Welt is presented to the lasted insole and upper in a position exactly reversed from that in the usual Goodyear welt shoe. 'The unfinished face of the Welt is resented to the lasted insole and upper, an attached thereto'by a line of stitching running along thelower edge of the welt, the lower edge being understood to be-that edge which is lower in position as the welt is sewn to the inverted lasted shoe. been thus sewn to the lasted insole and upper, the upper edge of the welt is then bent over and outwardly, and stitched down upon the edge of the insole, the unfinished side of the welt lying against the outsole and the finished side belngpresented to view in the completed shoe.

Our invention contemplates the use of a welt guide of special form and the combination of such a welt guide with the usual After the welt has type of welt vand turn sewing machine whereby such machine may be adapted to sew the welt in a reversed position to'manufacture a waterproof shoe.

With the above objects in view the present invention consists ina welt guide attachment for a shoe sewing machine hereinafter described, asdefined in the claims.

In the drawings accompanying this application, we have illustrated a preferred form of our invention as applied to the wellknown Goodyear welt and turn machine which'is illustrated and described in the patent to French and Meyer No.

Oct. 8, 1889. It is to be understood, however, that our invention is equally applica- .ble to other types of welt sewing machines and that it can be otherwise embodied with out departing from the spirit of our invention.

In the drawings accompanying this .application Figure 1 is a side elevation of our improved welt guide as applied to'a Good; year welt and turn machlne, the shoe and 1 the welting being shown in cross section;

Figs. 2 and 3'are side and topv views, respectively, of the welt guide detached, the arrow in Fig. 3 showing the direction of feed of the welting strip; and 'Figs. 4 and 5 are cross sections, respectively, of'a lasted shoe after thewelt has been sewn to the upper 'and insole, and after the outsole has been stitched to the welt.

Referring to Fig. 1 of the drawings, 1 is the curved hooked needle, 2 the thread finger, 3 the sliding gage, et the needle guide segment and-5 the slide bar to which is attached the welt guide 6. The parts above described are constructed and arranged to operate in a well known manner substantially as set forth in the above mentioned patent to French and Meyer, and further description thereof is considered unnecessary p Illustrated in Figs. 4 and ,5 is the type of shoe in connection with which our welt guide is designed to ,be used. Attached to the last 7 is the insole 8 and stretched over the lastis the upper 9. The lasted insole andupper are presented in'an inve'rted position by the operator to the welt sewing machine, and the welt l0 is-stitched against the lasted upper and insole in a reversed position, the unfinished side of the welt lying the slide 'bar 5.

against the margin of the upper 9 and stitched thereto at its lower edge 11 as shown in Fig. 4. After the welt has been so stitched to the insole and'upper, the up per edge 12 of the welt is turned over and outwardly, and then stitched down upon the edge of the outsole 13, the finished side of the welt thus being exposed in the finished shoe as illustrated in Fig. 5. The middle portion of the welt is thuscreased in, .filling and protecting the crease between the outsole and upper through which the water usually leaks in the ordinary type of shoe, and so making ashoe with a watertight inseam.

Through perforations 15 and 16 in the body portion 14 of the welt guide are thrust suitable bolts to attach l the welt guide to The bottom of the body portion 14 of the welt guides is formed with a transversely curved welt guiding surface 17, this-curved surface being shaped to form a shoulder 18, which, as the welt is. fed beneath it, will present a convexed surface of the lower edge of the welt against the upper and insole where the stitches are to be taken.

A sheet metal guide piece 19 of substantially the same shape as the welt guiding surface of the body portion 14 is attached to the body portion 14 by screws 20 and 21 forming between it and the body portion a welt receiving aperture 22. The welt guiding surface 17 of the body portion forms the top wall of this aperture while the bottom wall is formed by the sheet metal guide piece 19. The upper end of the sheet metal piece 19 is angled over at 23 forming that side wall of the aperture against which the upper edge 12 of the welt 1O bears.

edge 11 of the welt bears is formed by the guiding surface 24 of an elbow-shaped gage piece or spring 25. The arm 26 of this gage piece which forms the guiding surface 24 extends between the body portion 14 and the sheet metal guide piece 19, the other arm 27 of the gage piece being clamped, by means of an adjusting screw 29, in a slot 28 cut in the body portion 14. The gage 25 may thus be adjusted to accommodate welts of different widths. It will be noted that this adjustable gage-forms that side wall of the welt guide aperture which bears against that edge of the welting strip through which the needle passes. By the adjustment of the gage 25, the distance from the lower edge of the welt to the line of stitching may be Varied and hence the width of the edge part. of the welt which lies against the shoe upper beyond the line of stitching may be'fixed. The front of the upper portion of the welt guide body 14 is provided with'a notch or recess 30 through which the curved needle of the sewing ma- The, other side wall against which the lower the welt to a lasted insole and upper,

stitch forming mechachine passes in its movement to andfrom the work. This notch or recess30 is directly over that side of the welt guiding aperture in which the lower edge 11 of the welt 10 is carried, the needle passing near the lower edge of the welt l0 and stitching it to'the shoe upper and insole, the upper portion of the welt being guided through the aperture 22 above the line of stitching As the welt 10 is fed through the welt guiding aperture the shoulder 18 presses down and feeds the lower edge of the welt against the lasted upper and insole, the needle forming the stitch through that portion of the welt pressed down by the shoulder 18. After the welt shoe by the above described operation of the welter, as shown in Fig. 4, it is then turned over and stitched down upon the outsole as -illustrated in Fig. 5, forming a waterproof joint between the sole and upper.

Having thus described the invention what is claimed is j 1.
